Not every experiment that looks perfect on a whiteboard works in the real world. Kameron Tanseli, Head of Growth Engineering at @fyxerofficial, learned this the hard way. Fyxer has a scheduling feature — similar to Calendly. Kameron hypothesized that when someone booked a meeting through it, sending a booking confirmation would drive them back to Fyxer to sign up. Clean growth loop. Logical assumptions. Launched the experiment. Users pushed back immediately. "Why are you sending me a booking confirmation? I already got the Google Calendar invite and the Outlook invite. Now you've given me a third email." The entire value proposition of Fyxer is reducing inbox noise. And here they were adding to it. They killed the experiment fast — and pivoted to a different approach. That's the point of experimentation. Not every idea that makes sense in theory survives contact with real users. The teams that learn this fast are the ones that win. At Fyxer, 75% of experiments fail. Kameron calls that a feature. Every failure is a bullet dodged before it shipped to everyone. What's the most counterintuitive experiment failure you've ever seen?
